"Slip on a shirt
Slop on sunscreen
Slap on a hat"................as they say in Australia
and slide on some sunnies, as they recently added.
Your eyes are something like 30 times more susceptable to the sun than your skin is, so to avoid cataracts later on in life, always wear shades when in the sun, particularly when taking anti-biotics or anti-inflamatorys (Ibuprofen etc) as these can cause increased photosensitivity, which you may not notice on your skin, but could be affecting your eyes.
